Institute Mission, Goals, Results
The Iowa State University motto “science with practice” captures the central theme of PPSI—promoting the application and translation of intervention science into community practice to improve people's health and well-being.

To conduct innovative research promoting capable and healthy youth, adults, families, and communities—through partnerships that integrate science with practice.

  • To study the effects of evidence-based prevention, positive youth development, and health promotion interventions for youth, adults, families and communities;
  • To examine factors influencing youth, adult, and family involvement in evidence-based prevention and health promotion interventions and intervention research projects;
  • To evaluate the quality and sustainability of school-community-university partnership networks for widespread implementation of evidence-based prevention, positive youth development, and health promotion interventions.

Results—what we’ve found:*

Tested interventions are effective, based on randomized, controlled studies; we have found—
  • Long-term reductions in substance use
  • Long-term positive effects on school engagement and academic success
  • Long-term conduct/behavior problem reduction
  • Positive youth protective factor and skills-building outcomes
  • Economic benefits (e.g., $9.60 return on every dollar invested)
School-community-university partnerships are an effective way to deliver evidence-based** interventions; we demonstrate—
  • Consistently high implementation quality
  • Consistently high intervention recruitment and retention rates
  • Sustainability of the interventions
  • Successfully implemented cultural adaptations
School-community-university partnerships are an effective way to evaluate evidence-based interventions; we show—
  • High levels of school recruitment and retention across studies
  • High sample quality across studies
  • Successful assessment of approximately 30,000 individuals—most of them longitudinally
  • Rigorous methods that support strong conclusions

IMPACT Framework for School-Community-University Partnership Network
Linking public education systems and other service systems to ensure sustainable interventions and outcomes

Our partnership framework emphasizes the role of Land Grant University Extension agents in linking public school personnel—who aim to implement proven programs for their students and families—with resources outside of the school, to promote health and well-being among youth and families. Extension staff serve as linking agents like those described in Everett Rogers’ Diffusion of Innovation Model. Our emphasis is on sustained, quality implementation of evidence-based interventions (EBIs).
